LSS1 to LSS6: what a decade of Large Scale Solar tells you about bidding to win.

The LSS6 request for proposals is live — Pakej 1 and 2 closed on 7 August, and the Bumiputera-only Pakej 3 window opens on 17 August. Every bidder in it is, knowingly or not, betting against the pattern of the five rounds that came before. That pattern is worth twenty minutes of your attention, because it has been remarkably consistent: quotas grow, tariffs fall, and the qualifying bar rises — every single round.

Here is the decade in one table, then round by round: what each cycle changed, and what it taught the people who won.

The decade in one table

Figures are as reported by the Energy Commission, PETRA and industry coverage; early-round numbers vary slightly between sources depending on whether cancelled projects are counted. The shape of the story doesn't.

LSS1–LSS2 (2016–2017): the proof of concept

The first two rounds existed to answer one question: would competitive bidding beat the old Feed-in Tariff at scale? The answer was emphatic. Winning tariffs in the 34–65 sen/kWh range look expensive from 2026, but they were set against a FiT regime that had been paying considerably more for small systems. The rounds were modest — a few hundred megawatts each, split between Peninsular Malaysia and East Malaysia — and the winners were often landowners-turned-developers learning the trade.

The lesson that survives: early rounds reward participation; mature rounds reward specialisation. Several of today's listed solar names built their track record — the same track record LSS6 now demands — in these two unglamorous cycles.

LSS3 (2019): the price shock

LSS3 is the round the industry still talks about. With ~500 MW on offer, the lowest winning bid came in at 17.78 sen/kWh — below the marginal cost of gas generation and roughly half of what LSS2 had cleared just two years earlier. Module prices had collapsed globally, and bidders priced accordingly. Some winners later struggled to close financing at their own numbers, which taught the market a second, quieter lesson.

The lesson that survives: the winner's curse is real. A tariff that wins the bid but cannot survive the lender's sensitivity analysis is not a win — it is an option premium paid to discover your project is unbankable. This is precisely why bank-grade feasibility before bidding, not after, became standard practice among repeat winners.

LSS4 / MEnTARI (2020): scale meets stimulus

Tendered mid-pandemic as economic stimulus, LSS4 offered 1,000 MW and awarded 823 MW across thirty winners, deliberately spreading lots more widely. Tariffs settled in the ~15–26 sen/kWh band — the price shock of LSS3 institutionalised rather than reversed. With thirty projects racing similar CODs, the round also stress-tested the ecosystem: EPC capacity, grid-connection queues and module supply all tightened at once.

The lesson that survives: in a wide-award round, your competition isn't only at the bid box — it's in the queue for contractors, transformers and grid studies afterwards. Delivery capability became a bid-scoring reality from here on.

LSS5 and LSS5+ (2024–2025): scale up, lights down

The fifth cycle doubled the quota to 2,000 MW, drew bids far in excess of it, and awarded roughly 1,920 MW with CODs staged through 2026–2027. Its sequel, LSS5+, ran a year later with a two-package structure — 1.5 GW ground-mounted (30–500 MW lots) and a dedicated 500 MW floating solar package — and approved 1,975 MW from over 4,000 MW of bids: nearly two ringgit of demand for every ringgit of quota.

Two things changed beyond scale. Floating solar graduated from novelty to named package — a nod to Malaysia's constrained land near load centres. And, unlike every earlier round, the Energy Commission stopped publishing winner lists and tariff ranges. Analysts peg clearing tariffs in the mid-to-high teens of sen; officially, nobody knows.

The lesson that survives: you can no longer calibrate your bid against published clearing prices. Price discovery now happens inside your own financial model or not at all — which quietly raised the value of independent modelling and lowered the value of "last round plus a margin" guesswork.

LSS6 (2026): the hybrid round

LSS6, announced by PETRA on 16 July 2026, is the largest and most engineered round yet: 2,500 MW of solar paired with 1,250 MW of battery storage, targeted COD by 31 December 2029, and an expected RM13–15 billion of private investment. Three packages split the field:

• Pakej 1 — open tender, 2,200 MW solar + 1,100 MW BESS, bids of 60–500 MW per bidder;
• Pakej 2 — Bumiputera open tender, 300 MW solar + 150 MW BESS, same 60–500 MW bid band;
• Pakej 3 — Bumiputera small-scale, 150 MW solar without BESS, bids of 10–30 MW (RFP 17–28 August 2026).

The policy signals are unusually explicit. Hybrid solar-plus-storage is mandatory in the main packages — but BESS project experience is not required, only solar experience, an acknowledgement that almost nobody local has utility-scale BESS reference projects yet. Bidders using domestically manufactured PV modules get preference. And development is steered toward high-demand regions, explicitly the southern Peninsula — where data-centre load growth is concentrated.

What the decade adds up to

A decade in, LSS is no longer a solar programme with paperwork attached. It is a capital-allocation contest in which the engineering, the land, the financial model and the policy signals must agree with each other — and the rounds keep getting less forgiving of teams where they don't. LSS7 will come. The preparation for it starts with an honest read of your last bid.
